10．Doctors say anger can be an extremely damaging emotion，unless you learn how to deal with it．They warn that anger can lead to heart disease，stomach problems，headaches，emotional problems and possibly cancer．
（71）F Some people express anger openly in a calm reasonable way．Others burst with anger，scream and yell．But other people keep their anger inside．They can not or will not express it．This is called repressing anger．
For years many doctors think that repressing anger is more dangerous to a person's health than expressing it．They say that when a person is angry，the brain releases the same hormones （荷尔蒙）．They speed the heart rate，raise blood pressure，or sugar into the blood，etc．（72）A
Some doctors say that both repressing and expressing anger can be dangerous．They believe that those who express anger violently may be more likely to develop heart disease，and they believe that those who keep anger inside may face a greater danger of high blood pressure．
（73）G They say the first step is to admit that you are angry and to recognize the real cause of the anger，then decide if the cause is serious enough to get angry about．If it is，they say，"（74）E Wait until your anger has cooled down and you are able to express yourself calmly and reasonably．"
Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry．（75）B

A．In general，the people feel excited and ready to act．
B．They say that laughter is much healthier than anger．
C．Expressing anger violently is more harmful than repressing it．
D．Anger may cause you a cancer．
E．Do not express your anger while you are angry．
F．Anger is a normal emotion that we all feel from time to time．
G．Doctors say the solution is to learn to deal with anger．

9．Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises，according to scientists．They say that socializing and meeting with friends help increase levels of brown fat in the body which burns calories（卡路里）to produce heat．
Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks，even if they ate more．US researchers say that social excitement aids weight loss by turning white fat into brown．White fat stores calories and makes us fatter，while brown burns energy to produce heat．Turning white fat into brown is extremely difficult，normally requiring long-term stay in cold conditions or exciting part of the body's nervous system．
However，scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown．The team came up with their theory by studying the effects of various living environments on mice．Those，who lived alongside a greater number of mice，had more space and toys to excite themselves and then lost far more weight over the course of the study than their"couch potato"fellows．
Study author，Dr Matthew During，whose team's findings appear in the journal Cell Metabolism，said，"I'm still amazed at the degree of fat loss that occurs．"Explaining how new technology had threatened face-to-face socializing，he added，"It's not just a sedentary （久坐的）lifestyle and high calorie foods，but an increasing lack of social activities．"Co-author Dr Lei Cao said，"Loneliness is a potential factor for cancer and death； it's equal to cigarette smoking to a certain extent．Social activities are very vital．，

7．Bongos was a happy，artistic girl． She had one big ambition to play the drums in a band．But one big obstacle lay in her way．To be good enough to play in a band，Brenda had to practice a lot，but she lived next-door to a lot of old people．Many of them are sick．She knew that the sound of beating drums would really get on their nerves．So，she had tried playing in the strangest places：a basement，a kitchen，and even in a shower． But there was always someone it would annoy．
One day，while watching a science documentary on TV，she heard that sound cannot travel in space，because there's no air．At that moment，Brenda Bongos decided to become a sort of musical astronaut．
With the help of a lot of time，books and work，Brenda built a space bubble．This was a big glass ball connected to a machine which sucked out all the air inside． All that would be left inside was a drum kit（成套设备） and a chair． Brenda got into the space suit she had made，entered the bubble，turned on the machine，and played those drums like a wild child．
It wasn't long before Brenda Bongos came very famous．Many people came to see her play in her space bubble．Shortly afterwards she came out of the bubble and stated giving concerts．Her fame spread so much that the government suggested that she be part of a unique space journey．Finally，Brenda was a real musical astronaut，and had gone far beyond her first ambition of playing drums in a band．
Years later，when asked how she had achieved all this，she thought for a moment，and said："If those old people next-door hadn't mattered so much to me，I wouldn't have found a solution，and none of this would have ever happened．"

56．Why did Brenda try to play in the strangest places？B
A．Because she didn't want others to hear her play．
B．Because she didn't mean to disturb others．
C．Because she didn't have her own room．
D．Because she didn't like her neighbors．
57．Brenda started to give concertsA．
A．after she practiced in her space bubble
B．when she became part of the unique space journey
C．after she became a real musical astronaut
D．when people came to see her in the space bubble
58．Brenda became famous becauseC．
A．she was good at music and scienceB．she became a real musical astronaut
C．she invented a special way of practiceD．she played well and had a talent
59．It can be inferred from the text that"D"．
A．He laughs best who laughs last B．It's never too old to learn
C．Two heads are better than one D．One good turn deserves another．

6．You Are What You Eat
Genetic（基因的）engineering is the scientific change of the genetic material in a living organism． It allows scientists to identify specific genes，to remove them from an organism's chromosomes （染色体），improve them，analyze them，and possibly clone them，and to then reinsert the changed gene into the original organism，or a completely different organism．Unlike traditional breeding （繁殖），where a desired quality would be bred within the same species，genetic engineering can insert desired ones into organisms of different species．Wow…Did you catch that？
Genetic engineering creates many positive contributions to agriculture． For example，by genetically engineered（GE） foods，anti-cancer agents，minerals and vitamins can be increased．Improved taste，shelf life，and better transport are all possible．Also，GE plants can increase pest and bacterial resistance，therefore，making the food safe for consumers．
But some argue that the possible negative effects outweigh the positives，and critics are starting to voice their concerns． Unlike Europe，in the United States labeling is not required on genetically engineered foods or on foods that contain genetically engineered products． Most Americans do not realize that they are，in fact，eating GE foods．
The public is also concerned about the unknown health risks．With limited understanding of genes，scientists cannot predict possible effects．Because most genes introduced into GE plants come from sources not introduced into the human body，it is impossible to know if they will cause reactions． Moreover，due to the lack of labeling if allergies develop，it will be extremely difficult to find the origin of them．
There is also a major moral question in many minds．For many，the conflict is not if it is safe or not，but it disturbs them because it is unnatural and unnecessary．We are currently producing one and a half times the amount of food needed to feed the world，yet one in seven people are starving．GE food is unnecessary，and fails to address the root of hunger． Many believe that the only people who will benefit are the corporations that produce it．
Scientists cannot foresee t．he possible effects of GE foods，yet we eat them every day without even knowing it．We already have enough food，so why create more that could be potentially harmful to us，to the Earth and to all wildlife？I think that the benefits are amazing，but until we know for sure how these foods will affect us，they are not worth the risk．

5．Why Laughter Matters
Although most people believe that laughter is one of the nature's great treatments for a whole range of mental and physical diseases，it is still a serious scientific subject that researchers are trying to figure out．
"Laughter above all else is a social thing，"says Baltimore neuroscientist，Robert Provine，who has studied laughter for decades．"All laughter groups laugh‘ha-ha-ha'basically the same way．Whether you speak Mandarin，French or English，everyone will understand laughter．There is a pattern generator（发生器） in our brain that produces this sound．"
Laughing is our first way of communicating．Babies laugh long before they speak．No one teaches them how to laugh．They just do．People may laugh at a prank（恶作剧） on April Fools'day．But surprisingly，only 10to 15percent of laughter is the result of someone making a joke．Laughter is mostly about social responses rather to a joke．Deaf people laugh without hearing and people on cell phones laugh without seeing，showing that laughter isn't dependent on single sense but on social interactions．
And laughter is not just a people thing．Chimps tickle（挠痒） each other and even laugh when another chimp pretends to tickle them．
Jaak Panksepp，a Bowling Green University Psychology professor，studies rats that laugh when he tickles them．It turns out rats love to be tickled-they return again and again to the hands of researchers tickling them．
By studying rats，scientists can figure out what's going on in the brain during laughter．Northwestern University biomedical engineering professor，Jeffrey Burgdorf has found that laughter in rats produces a chemical that acts as an antidepressant（抗抑郁药）．He thinks the same thing probably happens in humans，too．This would give doctors a new chemical target to develop drugs that can fight depression．
Even so，laughter itself has not been proved to be the best medicine，experts said．Margaret Stuber，a professor at University of California，studied whether laugher helped patients．She found that distraction（分心） and mood improvement helped，but she could not find a benefit of laughter alone．
"No study has shown that laughter produces a direct health benefit，"Provine said，largely because it's hard to separate laughter from just feeling good．But he thinks it doesn't really matter："Isn't the fact that laughter feels good when you do it enough？"

67．The most important finding of Robert Provine's research is thatA．
A．laughter makes a person feel good
B．laughter depends on different senses

A．Patients will recover if they laugh enough．
B．Laughter is a means of communication as well as language．
C．A new medicine has been developed based on the laughter research．
D．Scientists can know what is happening in a human brain when he laughs．
